Becky and Tommy are asked to solve −4x − 25 = 8x + 15. Identify where one of them made an error. Becky Tommy −4x − 25 = 8x + 15 −4x − 25 − 8x = 8x + 15 − 8x −12x − 25 = 15 −12x − 25 + 25 = 15 + 25 −12x = 40 Negative 12x over 40 equals 40 over 40 x=negative three-tenths −4x − 25 = 8x + 15 −4x − 25 + 4x = 8x + 15 + 4x −25 = 12x + 15 −25 − 15 = 12x + 15 − 15 −40 = 12x negative 40 over 12 equals 12x over 12 x=negative ten-thirds

What is the ratio of 9 daises to 16 roses?

Answers

The ratio of 9 daises to 16 roses is 9:16 or also $\boxed{(9)/(16)}$

This cannnot be simplified any more because 9 and 16 are both perfect squares. :)

I believe it would be 9 to 16 which can also be 9 over 16 which cannot be simplified any more than it already has been hope this helps and its what you were asking for
